Cognifiy

Diagnosis Engine

Photo Upload

Snap a photo of your handwritten work. Cognifiy reads the question and each step of your solution.

Step-by-Step Diagnosis

Identifies the first incorrect step—not just if the final answer is wrong. Maps errors to specific concept gaps.

Confidence Gating

If the system isn't confident in its diagnosis, it regenerates or asks for clarity. No guessing, no hallucinated explanations.

Practice & Repair

Targeted Practice

Generates questions for your specific weak concept—same skill, different numbers. Not random topic-wide drilling.

Mistake Memory

Every error is logged. Recurring gaps get priority. The system builds a persistent profile of what you struggle with.

Foundation Repair

Structured tutor mode for persistent gaps: step-by-step lessons with confirmation, not chat loops.

Mastery & Retention

Mastery Tracking

Per-topic mastery percentage based on accuracy, time, and consistency. Watch weak areas become strengths.

Spaced Repetition

After mastery, topics return at optimal intervals (3 days, 3 weeks). Performance drops trigger active practice.

Weak Areas Dashboard

Visual overview of your identified gaps, mastery levels, and what needs attention next.

Visual & Interactive

Graph Practice

SVG-based interactive graph assessments: plot points, identify intercepts, construct functions.

Visual Feedback

Clear visual highlighting of errors, correct steps, and concept connections in your work.

Mobile Friendly

Works on any device. Upload photos directly from your phone camera.

Security & Privacy

Upload Protection

Type validation, size limits, EXIF stripping, randomized file names, private storage.

Account Security

Bcrypt password hashing, CSRF protection, secure sessions, login rate limiting.

Data Minimization

Store results, not raw noise. Old uploads auto-deleted. No unnecessary data collection.
